Creating PDFs using Microsoft Word

Hi guys

Many great websites like “oracle base” let you copy the content from their site, so that you can make documents for offline references. Obviously, you need to copy, paste make sometimes format a bit here and there so that the document finally becomes worth keeping.

One of the major issues with most of the free PDF printers is the lack of ability to include the embedded urls. Once you find an interesting article and use a free PDF printer like “PDF Creator”, you will realize that whole the book marked urls are lost other than the links starting with http:// or www

With the recent versions of Microsoft Word software (Office 2010 & later) , Microsoft lets the users to save a word document as PDF, in addition to printing the documents as PDFs. So what are the main difference between printing and saving as a word document?

While printing, the engine discards all the embedded URLs and the end user gets a plain PDF file, and when saved as (From file Save as context) PDF, all underlying URLs are preserved as bookmarks and clickable links are created automatically.

Does it sounds interesting? Give it a try and let us know!

Local DNS Server using DD-WRT | Buffalo Routers

A local DNS will help a developer to access and test the applications across local network having to worry about hostnames (Especially mobile devices, where updating host files may force one to root the devices)

This time we will see how a local DNS could be setup using relatively cheap WIFI routers running DD-WRT firmware

I am using a Buffalo router that acts as a WIFI access point at my home.

image

Make sure you are running the latest available firmware for the device to insure maximum stability. Once the firmware has been updated to the latest, Click on Services and you will be landed on Services page. Setting up the local DNS is most effective when you have all your “Computers” have static IP allocation (As seen with below image)

 

image

Don’t worry about the lease time parameters, as long your computers are having static IP addresses, these entries work as ‘A’ records, letting you to access the computers by their name, instead of IP addresses.

Set Used Domain as “LAN & WAN” & provide a meaningful name to “Lan Domain”. This name will be appended to your hostnames when you do a simple ping like commands. For example, when I try to ping “rajesh-pc” from command prompt, “rajesh-pc.my.home” will be automatically generated incase if you set up parameter “expand-hosts” with Additional DNSMasq options (Check below image)

 

 

image

Save the settings & apply. You are all set to start using the local DNS server. Whenever you have a new host, access the services page and create a static host entry (one time) & your last device is accessible using a name, instead of IP addresses.

C# (CSharp, C-Sharp) Windows Active Directory last logon

Hi guys

Please note, many threads were referred in order to compile the script attached below & all I did was re-arranging in order for better reading/formatting

(And I insure that the script works under following scenarios:

  1. You are a domain administrator
  2. You are administrating Windows 2003 onwards Windows domain
  3. Your puter is connected to the domain network ;)

)

Referenced websites/threads

  1. http://stackoverflow.com/questions/15775264/searching-for-lastlogon-attribute-of-user-in-multiple-domain-servers
  2. https://www.codeproject.com/kb/security/lastlogonacrossallwindows.aspx#_comments
  3. http://codebeautify.org/csharpviewer (for formatting the C# code)

How to test the code

Start Visual Studio (I am using 2013 Professional edition, you can use any of the community editions to test the scripts)

Create a new C# Console Application and name it llogon (else you need to change the namespace name “llogon” according to the name you have chosen for your new project.

Add the following references to your project

  1. “Framework -> System.DirectoryServices”
  2. “Browse and add -> C:\Windows\System32\activeds.tlb”

}
string readableLastLogon = DateTime.FromFileTime(lastLogonThisServer).ToString();
Console.WriteLine("User: " + distinguishedName + "Last logon: " +readableLastLogon);
}
}
Console.ReadLine();
}
}

}
}
}

Android | Lollipop | Annoyance with voice search

Update(4th October 2015): Additional steps

  • Disable the google app from settings (that will uninstall the app)
  • Restart the phone
  • Enable and update to most recent
  • Make sure the google search & now settings as intact as listed below
  • Reboot the device

I hadn’t had issues with voice search popping up while the headphone plugged in once after the above method(s) applied. Once again am not guaranteeing that every smartphone will get benefited with the above hacks.

Constantly getting a fit because your google voice search pop-ups frequently whenever you plug in a headphone? Are you using Lollipop? Try the following. Try to follow the instructions given below. I don’t guarantee this workaround mentioned with few of the android tech sites going to workout for everyone and for every device running lollipop. I am using Micromax Silver 5 running a forked(?) version of Cynogenmod ROM (I believe). Yet, there is nothing wrong giving it a try, right?

  1. Long press an empty area of one of your home screen
  2. Screenshot_2015-09-27-11-46-14
  3. touch the 3 dots in pyramid formation
  4. Should bring up the following screen
  5. Screenshot_2015-09-27-11-46-20
  6. Default the Search Bar comes as ON, turn it off
  7. Go to google app settings and touch “Voice” tab
  8. Screenshot_2015-09-27-11-46-48
  9. Touch “Ok Google” Detection
  10. Make sure your settings are something like below
  11. Screenshot_2015-09-27-11-47-01

this should do the trick, or minimum it has worked for me so far. I am yet to go on a longer drive. If the voice pop-up happens, I think I will brick this phone with a brick.

Cheers guys,

Teaser | Visual Studio | VB.Net & Oracle Database

t1

Okay, my last few posts were all about VB.Net & utilities for Windows domain administrators. Doesn’t mean that I stopped being a Oracle bouy ;) I still earn my salary for the Oracle job I do everyday at work and once after managing to purchase a legal copy of Visual Studio 2013 Professional Edition, I am committed to develop few sample applications using VB.Net & Oracle database.

So, stay tuned

VB.Net | Appending an existing XML file

VB.Net | Appending an existing XML file

XML is widely used by .net oriented programming. It is vast and learning XML could be requiring loads of dedication. I needed to add a XML file to hold certain configuration details that could be read with one of the VB.Net projects currently I am busy with. This project deals with running Oracle VirtualBox VM(Virtual Machines) headless using a Windows Service as Local System so that multiple administrators could log in and log off from the Windows Server that hosts Virtual machines without closing down the machines abrupt (This project is ongoing, half cooked)

Without wasting more time, let us see how to append an “existing” XML file using VB.Net

Create a Windows Form Project
Create a XML file (MyVMS.xml) using your favorite text editing tool and copy the below

[code language=”xml” gutter=”false”]
<?xml version="1.0" encoding="utf-8" standalone="yes"?>
<VM>
<MACHINE>
<MACHINE_ID>1</MACHINE_ID>
<VM_NAME>MyVM</VM_NAME>
<VM_SHUTDOWNMODE>poweroff</VM_SHUTDOWNMODE>
</MACHINE>
</VM>
[/code]
and copy the XML file to the project root folder

Add the namespaces to your new project

[code language=”vb” gutter=”false”]
Imports System.Xml
Imports System.Data
[/code]

As I said in the beginning, we will be adding data to an “existing” XML file, hence the XML files must have a root element, for example

[code language=”xml” gutter=”false”]
<?xml version="1.0" encoding="utf-8" standalone="yes"?>
<VM>
</VM>
[/code]

Drag a button to your forms1.vb design view
Drag another button to your forms1.vb design view
Drag a DataGridView to your forms1.vb design view

Now we will try to add one more “MACHINE” node into the existing XML file using VB.Net code block

[code language=”vb” gutter=”false”]
Public Class Form1

Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
Dim xmldoc As New XMLDocument()
Try
xmldoc.Load("MyVMS.xml")
Dim e1 As XmlElement = xmldoc.CreateElement("MACHINE")
Dim e2 As XmlElement = xmldoc.CreateElement("MACHINE_ID")
e2.InnerText = "2"
Dim e3 As XmlElement = xmldoc.CreateElement("VM_NAME")
e3.InnerText = "Linux"
Dim e4 As XmlElement = xmldoc.CreateElement("VM_SHUTDOWNMODE")
e4.InnerText = "savestate"

e1.AppendChild(e2)
e1.AppendChild(e3)
e1.AppendChild(e4)

xmldoc.DocumentElement.AppendChild(e1)
xmldoc.Save("MyVMS.xml")

Catch ex As Exception
MsgBox(ex.Message)
End Try
End Sub

Private Sub Button2_Click(sender As Object, e As EventArgs) Handles Button2.Click
Dim xmlFile As XmlReader
xmlFile = XmlReader.Create("MyVMS.xml", New XmlReaderSettings())
Dim ds As New DataSet
ds.ReadXml(xmlFile)
DataGridView1.DataSource = ds.Tables(0)
DataGridView1.Columns(0).HeaderText = "Id"
DataGridView1.Columns(1).HeaderText = "VM Name"
DataGridView1.Columns(2).HeaderText = "Shutoff Mode"

End Sub
End Class
[/code]

Now, as you click on the first button, a new node for “MACHINE” will be inserted using the static information attached & by activating the second button, your data grid view should populate the MACHINE information already stored within the XML file.

Pretty simple & easy, right? You may rush ahead and say thanks to my dearest friend and ONE of the best .Net programmers Aziz Marafi / @azizane , who had coded majority of the block above for the “FileMyster” project.

Please post your comments and queries and I may learn few more things with you!

VB.Net | Get IP address of a computer against hostname | Fun projects

Credits: http://stackoverflow.com/questions/19713868/returning-ipv6-instead-of-ipv4-in-vb

How to?

Open Visual Studio IDE (We are using VS 2012 Express and the .Net framework is 4.5 by default, hence if few things do not work at your setups, please cross check the specs we specified) and create a Windows form application. We’ll be mostly doing our samples using forms, a better mechanism to test stuffs against console applications (Minimum from our experiences)

drag a button to the form

drag a listbox to the form

& do not change any property for any of the above items

right click on the form and select view code, once the code page opens
Ctrl+A (Select all and delete)

copy and paste the below code block (replacing the original content of the code page)

[code language=”vb” gutter=”false” wraplines=”true”]
Imports System.Net

Public Class Form1
Public Function getip(ByVal lst As ListBox) As ListBox
Dim hostEntry = Dns.GetHostEntry("hostname")
Dim addressList As New List(Of IPAddress)

For Each address In hostEntry.AddressList
If address.AddressFamily = Sockets.AddressFamily.InterNetwork Then
lst.Items.Add(address)
End If
Next
Return lst

End Function

Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
getip(ListBox1)
End Sub
End Class
[/code]

Now replace the “hostname” with some actual hostnames and execute the application by pressing F5. Click the button over the form you are done! Please note, this sample is restricted to fetch IPV4 addresses.

VB.Net | Active Directory | Windows Form Application for listing users & details in a grid view

Have you read our previous post about finding last logon date time value for a domain member computer or user yet? If not, please read about it here

Now, we are going to provide you a decent (Warning: Amateurish code blocks possible) Windows forms based application that could list all your domain users and few of their details including last logon date time values.

run

Above image demonstrates the run time interface of the application. Application has a search textbox, that could accept values before and after the user details are populated.

Before the population, the users will be limited to matching string, after population, the list could be refined against the combination of keystrokes
